   1GIT v1.5.5 Release Notes
   2========================
   3
   4Updates since v1.5.4
   5--------------------
   6
   7(subsystems)
   8
   9 * Comes with git-gui 0.9.3.
  10
  11(portability)
  12
  13 * We shouldn't ask for BSD group ownership semantics by setting g+s bit
  14   on directories on older BSD systems that refuses chmod() by non root
  15   users.  BSD semantics is the default there anyway.
  16
  17 * Bunch of portability improvement patches coming from an effort to port
  18   to Solaris has been applied.
  19
  20(performance)
  21
  22 * On platforms with suboptimal qsort(3) implementation, there
  23   is an option to use more reasonable substitute we ship with
  24   our software.
  25
  26 * New configuration variable "pack.packsizelimit" can be used
  27   in place of command line option --max-pack-size.
  28
  29 * "git fetch" over the native git protocol used to make a
  30   connection to find out the set of current remote refs and
  31   another to actually download the pack data.  We now use only
  32   one connection for these tasks.
  33
  34 * "git commit" does not run lstat(2) more than necessary
  35   anymore.
  36
  37(usability, bells and whistles)
  38
  39 * Bash completion script (in contrib) are aware of more commands and
  40   options.
  41
  42 * You can be warned when core.autocrlf conversion is applied in
  43   such a way that results in an irreversible conversion.
  44
  45 * A catch-all "color.ui" configuration variable can be used to
  46   enable coloring of all color-capable commands, instead of
  47   individual ones such as "color.status" and "color.branch".
  48
  49 * The commands refused to take absolute pathnames where they
  50   require pathnames relative to the work tree or the current
  51   subdirectory.  They now can take absolute pathnames in such a
  52   case as long as the pathnames do not refer outside of the
  53   work tree.  E.g. "git add $(pwd)/foo" now works.
  54
  55 * Error messages used to be sent to stderr, only to get hidden,
  56   when $PAGER was in use.  They now are sent to stdout along
  57   with the command output to be shown in the $PAGER.
  58
  59 * A pattern "foo/" in .gitignore file now matches a directory
  60   "foo".  Pattern "foo" also matches as before.
  61
  62 * bash completion's prompt helper function can talk about
  63   operation in-progress (e.g. merge, rebase, etc.).
  64
  65 * Configuration variables "url.<usethis>.insteadof = <otherurl>" can be
  66   used to tell "git-fetch" and "git-push" to use different URL than what
  67   is given from the command line.
  68
  69 * "git add -i" behaves better even before you make an initial commit.
  70
  71 * "git am" refused to run from a subdirectory without a good reason.
  72
  73 * After "git apply --whitespace=fix" fixes whitespace errors in a patch,
  74   a line before the fix can appear as a context or preimage line in a
  75   later patch, causing the patch not to apply.  The command now knows to
  76   see through whitespace fixes done to context lines to successfully
  77   apply such a patch series.
  78
  79 * "git branch" (and "git checkout -b") to branch from a local branch can
  80   optionally set "branch.<name>.merge" to mark the new branch to build on
  81   the other local branch, when "branch.autosetupmerge" is set to
  82   "always".  By default, this does not happen when branching from a local
  83   branch.
  84
  85 * "git checkout" to switch to a branch that has "branch.<name>.merge" set
  86   (i.e. marked to build on another branch) reports how much the branch
  87   and the other branch diverged.
  88
  89 * When "git checkout" has to update a lot of paths, it used to be silent
  90   for 4 seconds before it showed any progress report.  It is now a bit
  91   more impatient and starts showing progress report early.
  92
  93 * "git commit" learned a new hook "prepare-commit-msg" that can
  94   inspect what is going to be committed and prepare the commit
  95   log message template to be edited.
  96
  97 * "git cvsimport" can now take more than one -M options.
  98
  99 * "git describe" learned to limit the tags to be used for
 100   naming with --match option.
 101
 102 * "git describe --contains" now barfs when the named commit
 103   cannot be described.
 104
 105 * "git describe --exact-match" describes only commits that are tagged.
 106
 107 * "git describe --long" describes a tagged commit as $tag-0-$sha1,
 108   instead of just showing the exact tagname.
 109
 110 * "git describe" warns when using a tag whose name and path contradict
 111   with each other.
 112
 113 * "git diff" learned "--relative" option to limit and output paths
 114   relative to the current directory when working in a subdirectory.
 115
 116 * "git diff" learned "--dirstat" option to show birds-eye-summary of
 117   changes more concisely than "--diffstat".
 118
 119 * "git format-patch" learned --cover-letter option to generate a cover
 120   letter template.
 121
 122 * "git gc" learned --quiet option.
 123
 124 * "git gc" now automatically prunes unreachable objects that are two
 125   weeks old or older.
 126
 127 * "git grep" now knows "--name-only" is a synonym for the "-l" option.
 128
 129 * "git help <alias>" now reports "'git <alias>' is alias to <what>",
 130   instead of saying "No manual entry for git-<alias>".
 131
 132 * "git help" can use different backends to show manual pages and this can
 133   be configured using "man.viewer" configuration.
 134
 135 * "gitk" does not restore window position from $HOME/.gitk anymore (it
 136   still restores the size).
 137
 138 * "git log --grep=<what>" learned "--fixed-strings" option to look for
 139   <what> without treating it as a regular expression.
 140
 141 * "git gui" learned an auto-spell checking.
 142
 143 * "git push <somewhere> HEAD" and "git push <somewhere> +HEAD" works as
 144   expected; they push the current branch (and only the current branch).
 145   In addition, HEAD can be written as the value of "remote.<there>.push"
 146   configuration variable.
 147
 148 * When the configuration variable "pack.threads" is set to 0, "git
 149   repack" auto detects the number of CPUs and uses that many threads.
 150
 151 * "git send-email" learned to prompt for passwords
 152   interactively.
 153
 154 * "git send-email" learned an easier way to suppress CC
 155   recipients.
 156
 157 * "git stash" learned "pop" command, that applies the latest stash and
 158   removes it from the stash, and "drop" command to discard the named
 159   stash entry.
 160
 161 * "git submodule" learned a new subcommand "summary" to show the
 162   symmetric difference between the HEAD version and the work tree version
 163   of the submodule commits.
 164
 165 * Various "git cvsimport", "git cvsexportcommit", "git svn" and
 166   "git p4" improvements.
 167
 168(internal)
 169
 170 * Duplicated code between git-help and git-instaweb that
 171   launches user's preferred browser has been refactored.
 172
 173 * It is now easier to write test scripts that records known
 174   breakages.
 175
 176 * "git checkout" is rewritten in C.
 177
 178 * "git remote" is rewritten in C.
 179
 180 * Two conflict hunks that are separated by a very short span of common
 181   lines are now coalesced into one larger hunk, to make the result easier
 182   to read.
 183
 184 * Run-command API's use of file descriptors is documented clearer and
 185   is more consistent now.
 186
 187 * diff output can be sent to FILE * that is different from stdout.  This
 188   will help reimplementing more things in C.
 189
